FAQs for Clate
Will you come out to Clate?
Yes. Clate is within the area we cover, which takes in towns, villages and rural addresses. Our work covers the whole of Scotland, including the islands, where work is planned around ferry crossings. Let us know about access, parking and anything unusual about getting there when you book.
Is new build mastic in Clate guaranteed?
Every job comes with our 12-month guarantee, wherever it is. We are fully insured, and an ARBOMaster approved applicator.
Will you just run a new bead over the existing one?
No. The old sealant is cut out fully, the joint cleaned and primed where needed, and a new bead applied.
What should I tell you?
A short description and the location, plus photos if you have them. If we need more, we’ll ask.
Can you work on commercial sites?
Yes, regularly. Larger jobs can be planned room by room or area by area.
Where is Mr Mastic based?
Mr Mastic is based in Crawley. We cover Clate and the rest of the Shetland Islands, along with the rest of our area.
Will it make a mess?
We keep the work tidy. Nearby surfaces are protected, and the area is left clean when we finish.
Why has my new-build shower seal failed already?
There are generally two causes: movement as the house dries and settles, and sealant laid onto dust without primer. Cutting it out and resealing properly fixes both.
About our new build mastic in Clate
A new build should have a neat, sound bead at every joint. When the finish is smeared, patchy or already cracking, it’s worth putting right early, before water gets into the floor or walls. If you are dealing with joints pulling apart as timber shrinks and smeared, uneven beads picked up at snagging, we can put it right, on kitchens, bathrooms & en suites and skirting & floors alike.
Around smaller Scottish places like Clate, new homes tend to be single plots or small developments. Each needs its sealant and floor joints finished as carefully as on a big site.
You get a one-year guarantee, the same in Clate as everywhere else we work.

Surface by surface
Windows and doors
Internal joints between frames and plaster often crack as a new house dries. We remove cracked sealant and apply a flexible one that suits the frame.
Skirting and floors
New homes often develop a gap between skirting and floor. We seal it with a flexible sealant that copes with the movement.
How we quote for new build mastic
Some jobs are bigger than they look, and some smaller. The main factors:
- The number and length of the joints
- When we can work, for business premises
- The old material and how stubborn it is
- Any mould that needs treating
Homes and businesses are quoted the same way: how much there is to do, how we reach it and what it needs, along with when we can work on site. Ask us for a quote and we’ll go through it with you.
Helping us quote
Before you ask for a quote, have a think about:
- Where the property is
- What’s wrong with the joints now
- Access, such as stairs, a lift or height
- The rough size of the job
We quote each job on its own. Simply email us at info@mrmastic.co.uk and describe the job, and pictures are welcome.
Joints and finishes in Clate homes
Clate is within about 1 mile of the coast. Plot mastic on new homes near the coast takes more weather than it would inland, so any gaps are best picked up early. Work on the islands has to be planned around ferry crossings and the weather, so give us as much notice as you can.
For jobs in and around Clate, choosing the right material for each joint is as important as a tidy finish. Around Clate, as everywhere, new build mastic is only as good as the preparation behind it.
Clate is about 13 miles north of Lerwick, in the Shetland Islands. We provide new build mastic to homes and businesses in Clate. Our the Shetland Islands coverage runs to 63 places, Clate among them.

Looking after it afterwards
Looking after new joints is easy, and it makes a real difference:
- Don’t seal over failed sealant yourself
- Ventilate bathrooms well, especially in the first year
- Record problems with dated photos
- Report sealant problems to your builder during the snagging period
Leave the sealant for the cure time we give you before showering or bathing. Silicone is usually left for about a day before water reaches them.
Mould takes hold quickly in sealant that has gaps or lifted edges. Resealing before mould gets in saves a harder job later.
Why deal with it now?
A failed shower or bath seal in a new home lets water into floors and walls that are still drying out. Dealing with it early keeps the damage away from ceilings, floors and finishes. When the nearest tradesperson is a drive away, it’s tempting to leave a small leak, but water behind a failed seal does the most damage when nobody’s watching.
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, any mould to treat, and whether we need extra access for height. Your quote takes all of that into account.

What sealant work cannot fix
Before you book, it’s worth knowing the limits:
- Settlement cracks that need a surveyor
- Deciding who is responsible under a builder’s warranty

What we do, step by step
On the day, we look over the joints with you first. We protect the surfaces around the joints before any work begins. Most jobs take anything from a few hours to several days, depending on the number of plots. Outdoor work around Clate depends on the weather, as sealant needs a dry surface, so an outdoor job can move if the forecast changes. Indoor work goes ahead whatever the weather.
- First, the list of joints is agreed from your snagging sheet or plot schedule.
- The failed sealant is removed completely.
- We clean out the dust and grit left from the build.
- We prime where needed and apply a sealant suited to each joint.
- Each bead is tooled and the cure times explained.
Before we arrive
- Mention any leaks or damp you’ve noticed
- On commercial sites, let us know about site rules
- Clear the area around the work
